WINDOW.

Specification of Letters Patent.

Patented Apr. 11, 1911.

Application filed. October 18, 1909. Serial No. 523,169.

To all whom it may concern:

Be it known that I, AUGUST KRAUSE, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Windows, of which the following is a specification,reference being had to the accompanying drawings, forming part thereof.

This invention has reference to improvements in windows having slidablesashes.

The object of this invention is to so construct a window having one ormore slidable sashes that all of said sash or sashes may slide to andfrom a fixed point and that either sash may swing outward from saidpoint.

Another object of the invention is to facilitate the cleaning of windowsashes.

Another object of the invention is to so construct a window having twoslidable sashes that both of said sashes may be secured in line to closethe window.

Another object of the invention is to provide a window adapted toexclude dust.

Another object of the invention is to so construct a window having twoslidable sashes that both of said sashes may be counterbalanced by asingle weight.

Other objects of the invention will appear from the followingdescription.

The invention consists in the peculiar construction of the several partsof the window frame and of the sashes therefor.

The invention also consists in such other peculiar features ofconstruction and combination of parts as shall hereinafter be more fullydescribed and pointed out in the claims.

Figure 1, represents a front elevation of the improved window, parts ofthe same being broken away. Fig. 2, represents a cross sectional view ofparts of the same taken on line 2-2 Fig. 1 looking downward. Fig. 3,represents a vertical sectional view of parts of the improved windowtaken on line 33 Fig. 1 looking toward the left from said line, thepositions of the sashes, when closed, being shown in full lines and theswinging outward of the lower sash being indicated. Fig. 4, represents aside elevation of the window partially broken away the normally, lowersash being indicated as moved upward and the normally, upper sash beingin its lowermost position as when swung outward for cleaning. Fig. 5,represents a detail view of parts of the lower sash and one of itsguiding pawls.

Similar numbers of reference designat corresponding parts throughout.

As shown in the drawings in its preferred form the improved window framecomprises the stiles 5 and 6 connected by the cross members? and 8 toform a rectangular frame for the sashes and having the outer facingframe formed by the vertical members 9 and 10 the inner edges of whichdefine thewidth of the window opening and are provided with the verticalguide strips 11-12 while the inner faces of said members 9 and 10 arefurnished with headings 13 and 1 1, V shaped in cross section, as shownin Fig. 2. Cross member 7 has an outer strip 15 and the bevel strip 16,spaced from said strip, while the cross member 8 has the jamb 17.

The stiles 5 and 6 are furnished with sockets 18, 18, 19, 19, and 20,20, arranged in pairs, and said members have at their lower portions thecurved guides 21, 22 and, at their upper portions, the straight guidestrips 23, 24: the lower ends of which are bevel, as shown in Fig. 3,and just below said bevel ends are pivotally mounted the pawls 25 and 26having upper bevel ends .which are adapted to be engaged with the bevelends of the guide strips 23 and 24: whereby said pawls may be alinedwith said guides. Below the pivots of said pawls 25 and 26 are mountedthe sash cord guides 27 and 28, herein shown as rotatable sheaves.

The lower sash is formed by the side stiles 29, 29 having V shapedgrooves to receive the beads 13 and 14 of frame members 9 and 10, and bythe lower rail 30, shaped in crosssection, as shown in Fig. 3, to fitagainst jamb 17, and the meeting rail 31 having the lip 32 and, at itsends, having the curved shoulders 33, 3 1 forming the mouths of theslots 35, 35 which extend from said mouths downward along the sides ofthe stiles 29, 29 and with which the pawls 25 and 26 are normallyengaged. On the fronts of said stiles 29, 29 near the shoulders 33, 34are pivotally mounted the plates 36, 36 whichwhen swung upward, asindicated in Fig. 3 act against the pawls 25 and 26 to swing the sameupward out of engagement with said shoulders 33, 34. In bearin s mountedon said stiles 29, 29 are journale the shafts 37, 37 having the offsetends, 38, 38 adapted to be engaged in the sockets 20, 20, and thehandles 39, 39. On the lower rail 30, are mounted the slidable pivotbolts 40, 40 adapted to be engaged in the sockets 19, 19 when the lowersash is approximately at its lowest point of movement.

The upper sash has the stiles 41, 41 connected by the upper rail 42,shaped to fit tightly between the bevel strip 16 and the strip 15, andby the lower or meeting rail 43 which is shaped to receive lip 32 of themeeting rail of the lower sash, said rail has also slidable bolts 44,44, adapted to be engaged in either of the pairs of sockets 18, 18 or19, 19. The stiles 41, 41 have grooves fitting the beads 13, 14, in Fig.2, and said stiles are furnished with plates against the edges of themetal guide strips 11 and 12 but which are free to swing past the lowerends of said guide strips when said upper sash has been moved downwardsufficiently. Secured to the left hand stile 29 is the cable 47 whichextends through a perforation in frame member 7, over the sheave 48 andon groove of sheave 49, around one of the grooves of sheave 50,rotatable in frame 51, back over one groove of sheave 52, over sheave 53and through frame member 7 and is attached to the left hand stile 41 ofthe upper sash. Cable 54 is secured to the right hand stile of the lowersash and passes upward through the frame member 7, over the other grooveof sheave 49 over the other of the pair of grooves in sheave 50, offrame 51, over the other groove of sheave 52, down through frame member7 and is fastened to the right hand stile of the upper sash. Frame 51has, in addition to sheave 50, the grooved sheave 55 over which thecable 56 is led, one end of this cable being secured to the stile 6 ofthe window frame and the other end of which is provided with thecounterbalance weight 57. The above mentioned sheaves 48, 49, 50, 52,53, and 55 are preferably made of glass to avoid noise, and arerotatably mounted.

With both sashes in the positions shown in Figs. 1 and 3, the rail 42 ofthe' upper sash fits closely between strip 16 and jamb 15 and thepressure exerted by offset ends 38 of bolts 37 in the sockets 20 whensaid bolts are rotated by the swinging upward of their handles 39,effects the pressing of both sashes against the V shaped beads 13 and 14and the rails 30 and 31 against their opposed parts so that the window,in this position, is practically closed against the entrance of dust. Atthis time the bolts 40, 40 are preferably secured in the sockets 19, 19.

Bolts 37 are slidable in their bearings for a limited degree and, whenit is desired to open the window, the handles 39, 39 are swung downwardand drawn toward each other to release the ends 38, 38 thereof from thesockets 20, 20, the lower sash is now free to swing inward, toward theinterior of the building, until the pawls 25, 25, engaged betweenshoulders 33, 34 of the lower, sash, are in line with their associatedguide strips 23, 23. If it is desired to slide upward the lower sash,bolts 40, 40 are released from sockets 19, 19 and said sash is movedupward, part of the weight thereof being balanced by the weight 57, theupper end of the sash being guided by the pawls 25, 25 to the guidestrips 23, 23 which ultimately receive the grooves 35, 35 of the stiles29, 29.

If, instead of moving upward the lower sash, it is desired to swing theupper end thereof inward, to the position indicated in Fig. 3, the bolts40, 40 are preferably entered in the sockets 19, 19 and the plates 36,36 are swung upward to lift the free ends of the pawls 25, 25 above theshoulders 33, 34 of the lower sash which sash may thereupon swing on theaxis of the bolts, 40, 40 until the cables 47, and 54 are engaged by thesheaves 27, 28 of the window frame stiles, and ride over said sheaves,in the further movement of the sash in this direction which movementmust be under a pressure sufiicient to overcome the action of weight 57.When the lower sash is in the raised position the bolts 44, 44 of theupper sash may be released from their sockets 18, 18 and the upper sashmay he slid downward until said bolts are in position to enter sockets19, 19 such engagement of these bolts 44, 44 permits the rotation ofsaid bolts in such sockets when the upper portion of this upper sash isswung inward to the position shown in full lines in Fig. 4 and, it willbe seen, that in said movement the cables 47 and 54 are intercepted bythe sheaves 27, 28 and ride over said sheaves while such swinging ofsaid upper sash is resisted by the weight 57. When the upper sash isswung backward into the window frame and its bolts 44, 44 are releasedfrom the sockets 19, 19 said sash may he slid upward to its closedposition. If now the upper sash he slid downward its bolts 40, 40 willbe intercepted bythe guides 21 and 22 and guided back to positions wheresaid bolts may be entered in the sockets 19, 19.

It is evident that various modifications may be made in the specificconstruction of the several parts, and in the combination of the samewithout departing from the spirit of this invention.

Having thus described my invention I claim as new and desire to secureby Letters Patent.
